WARSAW, Poland, April 16, 2025 — Researchers from the International Institute of Molecular and Cell Biology in Warsaw (IIMCB) described a new mechanism that improves the efficiency of mRNA-based therapies. The research findings will facilitate the development of novel therapeutics against cancers and infectious diseases. The scientific experiments were carried out at IIMCB, but important contributions also came from collaborators at the Faculty of Physics and Faculty of Biology of the University of Warsaw, the Medical University of Warsaw, and the Institute of Biochemistry and Biophysics of the Polish Academy of Sciences. The breakthrough study by the Polish researchers has just been published in Nature. 

This study conducts a comparative analysis of the standard-sample-bracketing (SSB) method and the double-spike (DS) method, aiming to provide practical recommendations to researchers for selecting optimal analytical approaches for natural samples. The DS method shows greater potential to reveal subtle Mg isotope fractionations in processes such as equilibrium inter-mineral Mg isotope fractionation, partial melting of magma, and the possible fractionation during crystallization differentiation. Continuous optimization efforts will further improve the versatility and accuracy of the DS method, particularly through expanding its application scope to incorporate more diverse standard samples. Such expansion is critical for thoroughly investigating the fundamental causes of analytical discrepancies between DS and SSB methods in Mg isotope studies.

In a paper published in National Science Review, a research team from Peking University presents new insights into magnetic field sensing. The study investigates the limits of quantum magnetometers and explores criteria for determining whether a magnetometer is essentially quantum.

Conventional thinking holds that the metal site in single atom catalysts (SACs) has been a limiting factor to the continued improvement of the design and, therefore, the continued improvement of the capability of these SACs. More specifically, the lack of outside-the-box thinking when it comes to the crucial hydrogen evolution reaction (HER), a half-reaction resulting in the splitting of water, has contributed to a lack of advancement in this field. New

research emphasizes the importance of pushing the limits of the metal site design in SACs to optimize the HER and addressing the poisoning effects of HO* and O* that might affect the reaction. All of these improvements could lead to an improved performance of the reaction, which can make sustainable energy storage or hydrogen production more available.

In a recent study, an international team of physicists, led by Prof. JO Gyu-Boong from the Department of Physics at the Hong Kong University of Science and Technology (HKUST) has made a significant observation of the BKT phase transition in a 2D dipolar gas of ultracold atoms. This groundbreaking work marks a major milestone in understanding how 2D superfluids behave with long-range and anisotropic dipolar interactions.
